Well,,,,,, very good questions POC,, here is what I do, and I am in no way suggesting you follow my lead this is just me and what I do. of my own planted stock I will pick my seeds and plant my seeds where ever I take a notion to. However in someone else woods(of wich I have attained permission) I always replant the seeds in the general vacinity, and I THINK that those requirements pertian to wild sang. If you are going to make a business venture out of this I would assume you would need a license or some permit in wich would be evidence enough for the warden should he ever stumble across your line. Now despite all this I suggest the best thang to do is actually contact the Indiana DNR and relay your concerns, it may take a week or so, but they will reply to you with an answer or direct you to someone who will. This way you got it straight from the horses mouth.
Good luck in your endeavors
